I have a Win2k3 server connecting to 1no. Win2k PC and 2no. Win98 PC's on a domain with Active Directory. I've physically connected another Win98 PC to the network and given it an fixed IP address. I've not logged in with any central user account, and it is part of a Workgroup. It seems to be able to access shared folders on the other Win98 PC's, can I prevent this?
